New build or upgrade?

[bigtrak]

After posting in the case central section earlier this week,

I'm now in two minds to just do a fresh build now with any parts that are worth keeping from my current pc,
Due guys think I can future proof my current rig much as well as put it in a smaller case or should I scrap and rebuild altogether?

I Want it to be able to play latest games so I know I will need at least a new gpu,
Problem is if I can I don't want to pour tons of cash into it, but I'm open to ideas,
know you guys are spot on when it comes to building

need it to fit in a smaller case which is top on the list due to the location of where my pc has got to go now due to the Mrs!

Any pointers guys?

I've got one already just for Windows but need to get a bigger size, and got plenty of storage also a nas, so that's not a problem.
I haven't clocked my cpu since buying it from new either so I suppose I could clock that a bit, also reason I posted was due to the size of my case, what brought me to the idea of upgrading or a new build.
Thanks just see that pointers on a good case also have you got some links for them cards and which is the best
